ABSTRACT
In a prospective study of 89 patients the postoperative corneal edema and endothelial cell count was studied after cataract extraction. A double blind investigation was performed as the patients during the first 6 postoperative days were treated with three different types of eye-drops: Maxidex, Pred-Forte 1% or placebo, all containing Benzalkonium Chloride 0.004%. The content of steroid in Maxidex and Pred-Forte was equivalent. We found no significant difference in estimates of endothelial cells in the three groups postoperatively. Corneal edema was less in the two groups treated with steroid. There was no significant difference between the two postoperative groups (p > 0.05) treated with Maxidex and Pred-Forte. The group treated with Pred-Forte showed significantly less postoperative corneal edema, calculated as the graphical area represented by the increase of central corneal thickness (CCT) after operation.

Fifty-one patients available for a 2 1/2 year follow-up after intracapsular cataract extraction and implantation of the semiflexible McGhan/3M, style 70 anterior chamber lens were evaluated for intraocular pressure (IOP). No significant change in the IOP could be demonstrated despite progression of iris-like tissue adhesions between the iris and lens haptics at or close to the trabecular meshwork. Four eyes (7.8%) had IOPs greater than or equal to 22 mm Hg without medication, and four other eyes used timolol eyedrops with subsequent IOPs less than or equal to 18 mm Hg. Eight eyes (15.7%) demonstrated an IOP increase greater than or equal to 25% over baseline pressures.

Morphological changes and lens position were examined in 51 patients 25 to 38 (mean 30) months after intracapsular cataract extraction (ICCE) with implantation of the semiflexible, 3M, style 70, anterior chamber lens. Morphological changes presumably associated with the ICCE proper were: iris transillumination defects (68.6%), rupture of anterior hyaloid membrane (20%), detachment of posterior vitreous (42.9%) and anterior synecchiae (13.7%). The implant-related morphological changes were caused by iris tucking (19.6%), small, mobile lenses causing endothelial disturbance (9.8%), iris-haptic adhesions and progressive ovalling of pupillary form. The present morphological changes were compared with a previously published examination of the same patients performed 4 months after surgery: 9 eyes without tissue changes around the lens feet at the previous follow-up now had iris-haptic adhesions involving from 1 to 4 lens feet. In 8 eyes the iris-haptic adhesions had progressed. Compared with the previous examination the fraction of eyes with tissue changes at the lens feet had risen from 47.1 to 64.7%, while the number of eyes with oval pupils had increased from 54.9 to 80.4%. Contact between lens haptic and iris root seems to constitute a constant stimulus for structural changes of the iris.

The results from 21 cases (in 19 patients) of conjunctivorhinostomy were evaluated. Twelve cases were successful. The operative technique and especially the need for meticulous post-operative care is discussed. A close post-operative follow-up is mandatory, since most of the failures were caused by loss of the Jones' tube.

A report is given of visual outcome and intraocular complications in 64 patients 3-8 months after implantation of anterior chamber lens. 80% had a final visual acuity of 0.50 or better. Visual acuity below 0.50 could in most cases be related to pathological findings in the eye independent of implant. Pupillary block was found in 4 cases (6%), and at re-examination they all had gonioscopic changes. The mechanism of pupillary-block-glaucoma with IOL lens implantation and measures to meet this is discussed. Gross tucking was found to pre-dispose to chronic inflammation. Cystoid macular oedema (3%) and retinal detachment (2%) was found without obvious relationship to gonioscopic changes.

Sixty-four patients were consecutively operated for senile cataract with implantation of the semiflexible McGhan/3M, style 70, anterior chamber lens. Intraocular pressure (IOP) was measured one day prior to the operation, 6 days and 3-8 months (mean 4 months) after the operation, and gonioscopy was performed one day prior to and 4 months after the operation. A significant fall in IOP was found in the operated eye 6 days after surgery. No significant change in IOP was found 4 months after surgery, neither in the operated eye nor in the non-operated fellow eye. Iris tucking seemed to have no influence on the post-operative tension, while a significant rise in IOP was found in 13 eyes with adhesions between the iris and lens haptics as the only abnormal gonioscopic finding.

Gonioscopy was performed in 64 patients 3-8 (mean 4) months after intracapsular cataract extraction with implantation of the semiflexible McGhan/3 M, style 70, anterior chamber lens. Iris tucking was present in 19 (30%) eyes. Iris-haptic adhesions (strands of iris-like tissue encircling the lens feet) were present in 24 (38%) eyes. Absence of iris tucking was statistically significantly (P less than or equal to 0.05) related to surgical expertise, while the occurrence of iris-haptic adhesions was independent of surgical experience. Pupillar deformation, usually an elongation in the axis of the implant, was present in 50%. The absence or presence of an abnormal gonioscopy could not with certainty be deduced from the form of the pupil. The majority of gonioscopically visible pathological changes in the chamber angle were located posterior to the trabecular meshwork.

An operation nurse repeatedly developed a corneal ulcer while mixing bone cement. It is suggested that the ulcer developed because of a composite effect of vapours from bone cement (methyl methacrylate monomer and hydroquinone), in spite of the fact that the Occupational Health Guidelines and the national threshold limit values for chemical substances had been respected. In-vitro and in-vivo animal studies are reviewed.
